I installed the latest catalyst drivers ( 6.14.10.6430 )recently, and have been having some weird problems with opengl. I tried the previous drivers, but the problem is the same. I'm not sure what the last working version was, as I deleted it....

heres the problem:

opengl hardware acceleration only seems to be enabled in fullscreen mode. A lot of apps that init gl in windowed mode throw errors:

Call of Duty single player exe (quake3 engine) complains about a lack of suitable pixel formats and stops dead on startup (while in the windowed console mode). Multiplayer works fine though, I think because it goes to fullscreen mode straight away.
